9 Claims.

This invention relates in general to a method of cooking meats, fish, fowl, and other materials, by means of a thin-walled container submerged in a liquid, such as oil or the like, which is heated above the boiling point.

An important object of this invention is in the provision of a new and improved method of cooking in a closed container at a high heat but not under pressure, and in relieving pressure from the container so that the material cooked is softened, tenderized, does not shrink but actually puifs or fiuffs up, producing a tasty and palatable food which is completely cooked in much less time than under the methods commonly employed at the present time.

A further object of the invention is in the provision of a cooking apparatus for carrying out this method which comp-rises a thin-wall metal container which is easily opened but need not be fluid-tight, and is provided with a discharge valve for relieving pressure from within the receptacle due to the heat of the liquid in which the receptacle is submerged for cooking.

A still further object of the invention is in the provision of a new and improved method of cooking which comprises the provision of a thin-wall container into which the material to be cooked is placed with a suitable amount of butter and immersed in a liquid heated well above the boiling point of water and left for a short time, depending upon the material and the heat of the cooking liquid so that satisfactory cooking can be effected by inexperienced help, and for cooking large quantities in a short space of time.

Other and further objects of the invention will appear in the specification and will be evident from the accompanying drawing in which,

Fig. 1 shows acooking receptacle in accordance with this invention;

Fig. 2 is a sectional view of the cooking unit shown in Fig. 1;

Fig. 3 is a view showing the cooking unit and means for submerging it in a cooking liquid; and

Fig. 4 is a detail illustrating the attachment of the cooking unit as shown in Fig. 3.

Inthe ordinary cooking of meats, fish, fowl and the like, they are either fried, baked or grilled, which tends to shrink, harden or encrust the foods, or they are boiled or stewed in the presence of water or other liquid. The process in any case is long and tedious, it requires expert attention at all times, and accurate timing by an experienced cook in order to produce desirable or satisfactory results.

The present method overcomes all of these objections by providing a method so simple that it can be done by inexperienced help following the simplest directions, and producing highly satisfactory results in a much shorter space of time. This method comprises the provision of a cooking liquid heated well above the boiling point of water, from 375 to 425 F. being a satisfactory temperature, in placing the meat or other material to be cooked in a substantially-closed thin metal receptacle with a small amount of flavoring'and cooking material such as butter, in immersing this closed receptacle in the hot liquid for a definite or predetermined time.

'Referring now more particularly to the drawings; a satisfactory receptacle for accomplishing this cooking operation comprises a flat, hollow receptacle formed of thin sheet metal having a top H! and a bottom H which fit tightly at the edges where they may be connected by screw threads 12 and It on the separate parts, or by any suitable. clamping or fastening means which holds the, parts together.

It is not necessary that the attachment of the threads or the other fastening means is entirely air-tight as the instant the receptacle is inserted within the hot cocking liquid a pressure is set up within the receptacle which tends to expel and prevent the entry of the cooking material so that when the cooking is in progress bubbles of air or steam are constantly discharging from the edges of the container. By having the walls ofthe container made of thin sheet metal, 24 gauge or thereabouts, heat is quickly conveyed to the contents of the container, thoroughly baking it and not tending to fry or boil it as would be the case with a thick metal receptacle.

In order to handle the container and to separate the parts a handle it is applied to the top and another handle 15 is applied to the lower edge of the bottom. By grasping these two handles or grips, usually protected by means of a pad or cloth, the parts may be separated even though highly heated.

Atone side of the top where it does not interfere with the, handle is a discharge valve IS with a discharge tube I'l leading upwardly therefrom to a suflicient height so that when the receptacle is immersed in a cooking liquid the upper end of the tube will be above the level of the cooking liquid. Also attached to and projecting upwardly from the. top is a holder I3 having a bent extremity. l9 forming a handle by means of which the receptacle may be inserted into and raised from the cooking liquid.

In. carrying out the method of this invention, a hot liquid pot or container 2!] may be provided for each cooking unitor receptacle or this container may be of sufficient length to receive a plurality of such cooking units. Any suitable means may be employed for holding each cooking unit submerged in the hot liquid with a space around the unit for free movement of the cooking liquid. A suitable arrangement as shown in Figs. 3 and 4 comprises a supporting rack or grid 2| spaced from the bottom of the cooking receptacle with a ledge or projection 22 at one side under which one edge of the cooking unit is inserted by means of the opposite handle I8 and the hand grip is then engaged underneath a lip or projection 23 at the opposite side of the receptacle 20, the height of a cooking liquid 24 extending Well above the top H) of the cooking receptacle so that it is entirely surrounded by the cooking liquid during the cooking operation. The liquid in the container is kept at a suitable or predetermined heat by any suitable burner 25.

closing material to be cooked in a thin-walled receptacle, immersing it in a liquid heated well above the boiling point of water and above 375 F., in relieving the pressure from within the receptacle by allowing vapor from the material cooked to escape from the receptacle, and Withdrawing the receptacle from the liquid after a predetermined In order to remove the cooking unit from the liquid container, the handle I9 is simply disen gaged from the catch 23, the container is raised from the cooking liquid, and the top is removed from the bottom of the container so that the contents in the bottom section are freely accessible for eating or by removal therefrom.

Any suitable liquid suchas oils, fats, grease, or even mineral oil, may be used for the cooking liquid 24 as this liquid does not come in contact with the food at any time, the heating of the liquid tends to prevent. it from entering the closed cooking receptacle, and the pressure within the receptacle excludes the liquid from the receptacle at all times during the cooking operation. 'When the receptacle is removed from the cooking liquid it may be necessary to shake or wipe the cooking liquid from the outside of the container.

Butter which is cooked with the contents of the receptacle blends with meats, fish, fowl, or other and softening the food, causing it to be uniformly cooked throughout and even chopped meats such as hamburger, are flufied or pufied out by this cooking rather than in the flat, hard, fried cakes as usually served. Thusa distinctive and pleasing flavor is imparted to'foods cooked in this manner.

We claim: 7
